I was busy tonight. Springs are out.
So here’s the math.
First of all the car is mostly together in terms of final weight. The following items are not in the car, I estimate the missing weight to be about 250-300 pounds…none of it is engine compartment.
door window glass and mechanisms
quarter window glass and some mechanisms
carpet and padding
rear seat
door interior panels
quarter interior panels
rear bumper and brackets
rear valance
most weatherstripping
convertible top fabric
originally new springs were 1.25 taller than old at rest, out of car.
now new springs are .75 taller at rest, so 6 months of driving and sitting with loose front end components has only settled 1/2 inch.
installed in the car, currently. the new springs are approximately 3 inches higher than old springs. In past wheels were slightly tucked into well, now wheels have 2.5 inches clearance from top of tire to well edge.
so here’s my current thought.
if I cut 1 winding, that will drop 2” immediately. That leaves the front end 1 inch higher than past ride height. The wheel should still have a half inch of air before fender/well… It gives room for future settling, and the added weight to come. I know I risk cutting too much, but I want to only do this once…I know the safe bet is cut half so they match old springs windings…
old spring almost 9 windings
new spring 9.5 windings.
thoughts, opinions, past experiences welcomed. I appreciate the input so far!
